So I haven't exactly figured out all the characters yet. I'm just gonna sort of wing it here but these are the ones I'm sure of right now. I just sort of went with my gut so don't be mad about the choices. Some might be a surprise😉Also, I know it says ST and IT cast but some characters may also be from other stuff.

(All characters aged up to the age of the movie characters)

Main characters:

y/n in Beca's roll

(Insert yo face)

Finn Wolfhard in Jesse's role

(Finn gets a gif cuz he's special ok)

Millie Bobby Brown in Aubrey's role

Sadie Sink in Chloe's role

Supporting characters:

Jack Dylan Grazer in Bumper's role

Gaten Matarazzo in Benji's role

Natalia Dyer in Gail's role (the female commentator)

Joe Keery in the John's role (the male commentator)

Side characters:
David Harbour in the role of y/n's dad

Dacre Montgomery in Luke's role (y/n's boss at the radio station)

Jaeden Lieberher in Donald's role

Sophia Lillis in Cynthia's role

Iris Apatow in Stacy's role

Lilia Buckingham in Lilly's role

The rest I'll probably just figure out along the way. Most will probably be random.

I've decided that Fat Amy is one of a kind so she will be playing herself.

Also some kind of famous people around their age might be making some cameos.

WARNING: Some cursing, some drug references, some sexual references. Nothing major, though. This is all mostly just fun and games.
